Janina Hakenmuller focused on configuration management and data processing optimization within the DUNE/dunesw and DUNE/dunereco repositories, using FCL for targeted improvements. She streamlined data processing by modifying configuration files to exclude deconvolved optical waveform data, which reduced file sizes and improved both processing and storage efficiency. In DUNE/dunereco, Janina enhanced configuration clarity by aligning file naming and generator labels with the Marley generator, and introduced a NuEScatter configuration to support geometry-based analysis. Her work demonstrated a methodical approach to configuration and data processing, delivering practical enhancements in analysis readiness and resource utilization over the course of the month.
